Automatic identification of people: improving the performance of dynamic signature verification

The problem of verifying the identity of people presenting to EDI or other electronic transactions terminals is becoming more important as the value manipulated by such systems and their use becomes more widespread. All techniques have their appropriate and overlapping application areas. However, the author concentrates on the use of writing-in particular the dynamics of the written signature.
